Determine if a line intersects a plane where 2 points for line, 3 points for plane
Hi, how can I determine if a line(given (x1,y1,z1),(x2,y2,z2) on the line) intersects a plane(given (x3,y3,z3),(x4,y4,z4), (x5,y5,z5) on the plane):confused:

Thanks helping.

While it's not hard, if you don't know cross products, dot products and parametric equations of lines, it's a long lecture.

I use this site along with the book "3D Math Primer for Graphics and Game Development" as my primary sources.
